It can't be the DHCP on the LinkSys at fault.

No. Fair point. What I meant to suggest is that possibly the router is dropping the packets on the floor. I don't know why it would, but until it's taken completely out ot the equation -- either by using a cross-over cable or a hub, it can't be discounted.

Actually, thinking about it, Hugo uses a Linksys router on his cable. His Receiver works. I'll ask him if his network topology is particularly different from this one.
